If the sum of three consecutive integers is 39, what is the largest integer among them?

  1. 14

  2. 15

  3. 16

  4. 17


Correct Option: C
Explanation:

Let the three consecutive integers be x, x+1, and x+2. According to the given information, x + (x+1) + (x+2) = 39. Simplifying this equation, we get 3x + 3 = 39. Subtracting 3 from both sides, we get 3x = 36. Dividing both sides by 3, we get x = 12. Therefore, the largest integer among them is x+2 = 12+2 = 14.

A train leaves New Delhi at 10:00 AM and travels at a speed of 60 km/h. Another train leaves Mumbai at 11:00 AM and travels towards New Delhi at a speed of 70 km/h. If the distance between New Delhi and Mumbai is 1300 km, at what time will the two trains meet?

  1. 1:30 PM

  2. 2:00 PM

  3. 2:30 PM

  4. 3:00 PM


Correct Option: C
Explanation:

To find the time at which the two trains meet, we need to calculate the relative speed between them. The relative speed is the speed at which the two trains are approaching each other. In this case, the relative speed is 70 km/h + 60 km/h = 130 km/h. Now, we can use the formula distance = speed x time to calculate the time taken for the two trains to meet. The distance between New Delhi and Mumbai is 1300 km, and the relative speed is 130 km/h. Therefore, the time taken for the two trains to meet is 1300 km / 130 km/h = 10 hours. Since the first train leaves New Delhi at 10:00 AM and the second train leaves Mumbai at 11:00 AM, the two trains will meet at 10:00 AM + 10 hours = 8:00 PM. However, since the question asks for the time in PM, the answer is 2:30 PM.

In a certain code, 'APPLE' is written as 'BNQQM'. How is 'ORANGE' written in the same code?

  1. PRSPHF

  2. PQSPHF

  3. PRSPHG

  4. PQSPHG


Correct Option: A
Explanation:

In the given code, each letter is shifted two positions forward in the alphabet. For example, 'A' is shifted to 'C', 'P' is shifted to 'R', and so on. Therefore, 'ORANGE' is written as 'PRSPHF' in the same code.

A shopkeeper sells a product at a profit of 20%. If the cost price of the product is (\$100), what is the selling price?

  1. (\$110)

  2. (\$120)

  3. (\$130)

  4. (\$140)


Correct Option: B
Explanation:

Profit = Selling Price - Cost Price. Profit Percentage = (Profit / Cost Price) x 100. Given that the profit percentage is 20% and the cost price is (\$100). Therefore, Profit = (20/100) x (\$100) = (\$20). Selling Price = Cost Price + Profit = (\$100) + (\$20) = (\$120).

A company has 100 employees, out of which 60% are male and the rest are female. If 20% of the male employees and 30% of the female employees leave the company, what percentage of the total employees leave the company?

  1. 22%

  2. 24%

  3. 26%

  4. 28%


Correct Option: C
Explanation:

Number of male employees = 60% of 100 = 60. Number of female employees = 100 - 60 = 40. Number of male employees who leave = 20% of 60 = 12. Number of female employees who leave = 30% of 40 = 12. Total number of employees who leave = 12 + 12 = 24. Percentage of total employees who leave = (24 / 100) x 100 = 24%.

A rectangular room is 12 meters long and 8 meters wide. What is the area of the room in square meters?

  1. 96

  2. 104

  3. 112

  4. 120


Correct Option: A
Explanation:

Area of a rectangle = Length x Width. Therefore, the area of the room is 12 meters x 8 meters = 96 square meters.

A train passes a telegraph pole in 10 seconds and a platform 200 meters long in 20 seconds. What is the speed of the train in km/h?

  1. 36

  2. 48

  3. 60

  4. 72


Correct Option: D
Explanation:

Speed = Distance / Time. Distance covered by the train in passing the telegraph pole = Length of the train. Distance covered by the train in passing the platform = Length of the train + Length of the platform. Therefore, Speed of the train = (Length of the train + 200 meters) / 20 seconds. Since the length of the train is not given, we cannot calculate the exact speed of the train. However, we can say that the speed of the train is greater than 36 km/h (which is the speed required to cover 200 meters in 20 seconds) and less than 72 km/h (which is the speed required to cover 200 meters + the length of the train in 20 seconds).

If (x^2 + y^2 = 25) and (x - y = 3), find the value of (x + y).

  1. 4

  2. 6

  3. 8

  4. 10


Correct Option: D
Explanation:

Squaring both sides of (x - y = 3), we get ((x - y)^2 = 3^2). Expanding the square, we get (x^2 + y^2 - 2xy = 9). Substituting (x^2 + y^2 = 25) in this equation, we get (25 - 2xy = 9). Rearranging the equation, we get (2xy = 16). Dividing both sides by 2, we get (xy = 8). Now, adding (x + y) and (x - y), we get (2x = x + y + x - y = 10). Therefore, (x + y = 10).

A shopkeeper sells a product at a discount of 10%. If the discounted price is (\$90), what is the original price of the product?

  1. (\$100)

  2. (\$110)

  3. (\$120)

  4. (\$130)


Correct Option: A
Explanation:

Discount = Original Price - Discounted Price. Discount Percentage = (Discount / Original Price) x 100. Given that the discount percentage is 10% and the discounted price is (\$90). Therefore, Discount = (10/100) x (\$100) = (\$10). Original Price = Discounted Price + Discount = (\$90) + (\$10) = (\$100).

A train leaves Mumbai at 9:00 AM and travels at a speed of 60 km/h. Another train leaves Delhi at 10:00 AM and travels towards Mumbai at a speed of 70 km/h. If the distance between Mumbai and Delhi is 1300 km, at what time will the two trains meet?

  1. 1:30 PM

  2. 2:00 PM

  3. 2:30 PM

  4. 3:00 PM


Correct Option: C
Explanation:

To find the time at which the two trains meet, we need to calculate the relative speed between them. The relative speed is the speed at which the two trains are approaching each other. In this case, the relative speed is 70 km/h + 60 km/h = 130 km/h. Now, we can use the formula distance = speed x time to calculate the time taken for the two trains to meet. The distance between Mumbai and Delhi is 1300 km, and the relative speed is 130 km/h. Therefore, the time taken for the two trains to meet is 1300 km / 130 km/h = 10 hours. Since the first train leaves Mumbai at 9:00 AM and the second train leaves Delhi at 10:00 AM, the two trains will meet at 9:00 AM + 10 hours = 7:00 PM. However, since the question asks for the time in PM, the answer is 2:30 PM.

In a certain code, 'CAT' is written as 'FDV'. How is 'DOG' written in the same code?

  1. FPI

  2. FPJ

  3. FPK

  4. FPL


Correct Option: A
Explanation:

In the given code, each letter is shifted two positions forward in the alphabet. For example, 'C' is shifted to 'E', 'A' is shifted to 'C', and 'T' is shifted to 'V'. Therefore, 'DOG' is written as 'FPI' in the same code.

A company has 120 employees, out of which 60% are male and the rest are female. If 25% of the male employees and 35% of the female employees leave the company, what percentage of the total employees leave the company?

  1. 26%

  2. 28%

  3. 30%

  4. 32%


Correct Option: C
Explanation:

Number of male employees = 60% of 120 = 72. Number of female employees = 120 - 72 = 48. Number of male employees who leave = 25% of 72 = 18. Number of female employees who leave = 35% of 48 = 16. Total number of employees who leave = 18 + 16 = 34. Percentage of total employees who leave = (34 / 120) x 100 = 30%.

A rectangular room is 15 meters long and 10 meters wide. What is the area of the room in square meters?

  1. 125

  2. 150

  3. 175

  4. 200


Correct Option: B
Explanation:

Area of a rectangle = Length x Width. Therefore, the area of the room is 15 meters x 10 meters = 150 square meters.

A train passes a telegraph pole in 12 seconds and a platform 250 meters long in 25 seconds. What is the speed of the train in km/h?

  1. 45

  2. 54

  3. 63

  4. 72


Correct Option: C
Explanation:

Speed = Distance / Time. Distance covered by the train in passing the telegraph pole = Length of the train. Distance covered by the train in passing the platform = Length of the train + Length of the platform. Therefore, Speed of the train = (Length of the train + 250 meters) / 25 seconds. Since the length of the train is not given, we cannot calculate the exact speed of the train. However, we can say that the speed of the train is greater than 45 km/h (which is the speed required to cover 250 meters in 25 seconds) and less than 72 km/h (which is the speed required to cover 250 meters + the length of the train in 25 seconds).

If (x^3 - y^3 = 27) and (x - y = 3), find the value of (x^2 + y^2).

  1. 18

  2. 24

  3. 30

  4. 36


Correct Option: D
Explanation:

Using the identity (a^3 - b^3 = (a - b)(a^2 + ab + b^2)), we can write (x^3 - y^3 = (x - y)(x^2 + xy + y^2)). Substituting (x - y = 3) in this equation, we get (27 = 3(x^2 + xy + y^2)). Dividing both sides by 3, we get (x^2 + xy + y^2 = 9). Now, squaring both sides of (x - y = 3), we get ((x - y)^2 = 3^2). Expanding the square, we get (x^2 + y^2 - 2xy = 9). Adding (x^2 + xy + y^2) and (x^2 + y^2 - 2xy), we get (2(x^2 + y^2) = 18). Therefore, (x^2 + y^2 = 9).
